9.1.3. Coupling check Removal

1. Remove a transmission.
2. One after another weaken fixing bolts of a press disk of coupling accordingly on 1–1,5 turns until the disk will be weakened press.

The prevention

If fixing bolts get out at once completely the spring can be damaged тарельчатая.

3. That simultaneously at easing of bolts the flywheel did not turn, stop its screw-driver.
4. After that completely unscrew bolts.
5. Take press a disk and a coupling disk.
The prevention

At extraction do not drop them, differently after assemblage there can be the difficulties connected with дерганьем and separation of coupling.

6. Blow compressed air a flywheel inside or wipe its rag moistened in gasoline.


1. Check up press a coupling disk on absence of cracks пережога and scratches.
2. Survey тарельчатую a spring on absence of cracks.
3. Check up on deterioration and uniformity of height ledges тарельчатой springs (arrow), if necessary cautiously level their pincers.

The prevention

Deterioration can make a maximum of 0,3 mm.

4. Check up a flywheel on absence of cracks пережога and scratches.
5. Process press a disk of coupling by a rough grinding skin.
6. Replace made oily, covered консистентной with greasing or mechanically damaged disks of coupling.
7. Measure a thickness of overlays of a disk of coupling. New: 3,6-4,0 mm from each party of an overlay. If the deterioration limit in 2,6-3,0 mm on each party of a frictional overlay is already reached, replace a coupling disk. As arrive in the presence of cracks on frictional overlays.
8. Check up on absence of wear tracks and grinding in lock bolts, amortisation windows, springs of torsion and the plug (arrows).
9. Remove and check up the bearing муфты deenergizings of coupling from a tubular support on a forward cover of a transmission.
10. In a repair truck it is possible to check up a coupling disk on palpation. Lateral palpation at a coupling disk can make a maximum of 0,5 mm.
The prevention

This check is required only in the event that it is necessary to establish again an old disk of coupling and coupling was incorrectly switched off earlier.


1. Spread a disk of coupling and press a coupling disk on a flywheel and centre their connecting стрежнем or aligning tool HAZET 2174.

The prevention

At engines with a two-case flywheel the gear wreath of a disk of coupling проникелирован and consequently does not require greasing.

2. One after another consistently tighten fixing bolts to a press disk of coupling on 1–1,5 turns until press the disk to the full will not be fixed. The inhaling moment: 25 Н.м. Then remove central оправку.
The prevention

Pay attention to that at a tightening of bolts press the disk in regular intervals and without agnails was involved in a flywheel.

3. Mount a transmission.
